SELF-HEATING: GAS-IRON.

Specification of Letters Patent.

Patented Jan. 6, 1914.

Application filed July 1912. Serial No. 707,381.

To all whom it may concern:

Be it known that I, Seams C. ROCKMAN, a citizen of the United States,residing at Philadelphia, in the county of Philadelphia and State ofPennsylvania, have invented certain new and useful Improvements inSelf-Heating Gas-Irons, of which the fol l wing i a pecificati Myinvention relates to self-heating gas irons.

The object is to construct such sad iron with a hollow body, and soconstructed that the bottom thereof will receive and take upsubstantially all the heat.

It also consists in adjustable means for confining the heat within thesad iron to the bottom and has means for preventing the escape offlames.

It further consists in certain improvements of construction whereby theheat within the body is fully transmitted to the bottom of the iron.

Figure 1 is a full side View. Fig. 2 is a rear-end view. Fig, 3 is aplan view with the cover removed. Fig. 4: is a sectional view at a. a.of Fig. 3 Fig. .5 represents a longitudinal section taken at the centerof Fig. 3. Fig. 6 represents a section of the nipple secured in theburner tube.

Similar numerals refer to similar parts throughout the drawings.

In the drawings, 1 is a handle secured to a yoke 2, which is secured toa cover 3 by means of screws or bolts 4; and nuts 5. Screws 4 extenddown and carry a deflector 6 by means of nuts 7 '7, so that thedeflector can be adjusted up and down, whereby the space between it andthe bottom part of the iron can be increased or decreased so as to allowfor the escape of different quantities of gases. The deflector 6 isprovided with a lining of asbestos .8 so as to prevent transmission ofheat to the cover of the iron. The deflector 6 is held by bolts 4: at anincline so as to afford the proper escape toward the exhaust exit 9 forthe gases.

10 represents ribs extending across the iron and terminating close tothe sides 11.

The central portion of the bottom of the iron at 12 is thin and formsbetween the thicker portions 13 and the ribs 10 pockets 14. The ribs 10are connected by ribs 15 so as to abstract all the heat of the gasesbefore escaping. The sides of the iron are cut at the top at 16 so as toallow the escape of gases above the deflector. 17 represents holes forair inlets along the sides of the iron, Which are located so as to letthe air in, in the center of each pocket.

18 is a burner povided with gas exit holes 19 so located near the ribs10 as to be within the pockets on each side of the air inlet holes 17 asshown on line a. a. of the burner.

The central rib 19 extends along the bottom, directly under the burner18 so as to prevent the gases from escaping from one side to the other.The ribs 10 are drilled so as to admit the burner 18 which is held n plae by a set screw 20,

The burner 18 is provided with a nipple 21 whi h is screwed into thesaid burner and by .mean of nut 22 can be adjusted 0 a t adju t the airinlet 2 to the burn 2a is a gas regulating screw whereby the gas passesthrough the nipple, and can be decreased or increased for the quantityof gas required, or for the quantity or richness of gas used in thedifferent localities.

To prevent the flame of the gas within the iron, from flashingback-through opening 23, I provide a wire gauze or screen 24'.

25 is a wire-screen secured to deflector 6 and bent so as to coverexhaust outlet openings .9, thereby preventing escape of flames.Openings 16 in the sides of the iron may also be screened by wire asshown at 26.

27 are grooves adjacent to the ribs 10 which augment the heat absorbingsurface so that all th heat generated in the combustion pockets orchambers 14; is quickly transmitted to the bottom of the sad-iron, so asto supply and .Inaintain the bottom heat While operating, or ironingdamp clothes. The ribs 10 and 15 on the thickened portion serve toabstract the remaining heat of the combustion before it escapes and willtransmit securely .to the body .of the iron.

Various changes may be made in the form and detail and arrangement of myinvention without departing from the spirit thereof.

Having thus described my invention, I claim 1. In a self-heating gasiron, a hollow body, a cover therefor, a handle, a deflector or guideplate for guiding the exhaust gases rearward, bolts passing through thecover and handle, nuts on said bolts for securing the handle to thecover, and nuts on said bolts for adjusting the height of either end andthereby the inclination of said guide plate.

2. In a self-heating gas iron, a hollow body, a cover therefor, ahandle, a deflector or guide plate for guiding the exhaust gasesrearward, bolts passing through the cover and handle, nuts on said boltsfor securing the handle to the cover, and nuts on said bolts foradjusting the height and incline of said guide plate, an exhaust outletin the wall of the iron, a screen secured to said plate, said screenextending upward to the top of the exhaust outlet and to the cover, anddown over the exhaust outlet for the purpose of preventing flames andhot combustion products from reaching the cover and escaping over theplate, and for preventing the flames escaping to the exhaust outlet,from burning or scorching the material respectively, said screen beingin one piece.

3. In a self-heating gas iron, a hollow body, a cover therefor, anadjustable exhaust guide plate for directing the exhaust from the body,an exhaust outlet, a screen secured to said plate for preventing flamespassing over the said plate and through the exhaust outlet respectively.

4. A self-heating sad iron having a hollow body, provided with alongitudinal depression and lateral air inlets, transverse heatabsorbing and conducting ribs, longitudinal heat absorbing ribs integralwith said transverse ribs, recesses or grooves adj acent to thetransverse ribs, a longitudinal bottom rib, holes in the transverseribs, a burner passing through said holes, said transverse ribs andbottom rib dividing said depression into combustion pockets or chambers,a removable cover for the said iron, an exhaust outlet, and anadjustable exhaust directing and heat retaining plate within the body.

5. A self-heating sad iron having a hollow body, provided with alongitudinal depression and lateral air inlets, transverse heatabsorbing and conducting ribs, longitudinal heat absorbing ribs,integral with said transverse ribs, recesses or grooves in the bottomadjacent to the transverse ribs, a longitudinal bottom rib, holes in thetransverse ribs, a burner for said iron located within the depressionand passing through said holes, downwardly directed exit holes in saidburner, and said exit holes in the burner being staggered with the airinlets in the iron, said transverse ribs and bottom rib forming with thebottom and walls on the raised portion of the bottom, and sides thereof,heat absorbing and conducting means, an adjustable heat entraining platecovering all ribs within the body for confining the heatto the ribs andto the bottom of the iron.

6. In a self-heating sad iron, a hollow body having its bottom providedwith a central rib and side or lateral raised portions, transverse ribsintegral with said raised portions and said central rib, said sideportions having grooves adjacent to the transverse ribs, holes in thetransverse ribs, and a burn-er passing through said holes adjacent tosaid central rib.

7. In a self-heating gas iron, a hollow body, the bottom of which has acentral rib and side raised portions provided with grooves, adjacent tothe central rib, ribs integral with said side portions, adjacent to theouter walls of the iron; heat absorbing and conducting ribs integralwith the raised portions and the side ribs and an adjustable deflectorextending over said raised portions and over all the ribs for thepurpose of retaining the heat and confining the heat between said ribsand to the bottom of the iron.

8. In a self-heating gas iron, a hollow body having a bottom with acentral rib and with grooved raised side portions, said grooved sideportions being thicker than the central rib, a burner centrally locatedand substantially below the top of said grooved side portions.

9. In a self-heating gas iron, a hollow body, having a bottom with acentral rib and also laterally grooved side portions, a burner centrallylocated and substantially below the top of the said grooved sideportions.

In testimony whereof I ai'lix my signature in presence of two witnesses.
